CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 570,004, dated October27, 1896.

Application filed August 5, 1896- Serial No. 601,748. (No model.)

To (tZZ whom it man concern:

Be it known that I, NOAH FRANKLIN CORNE, a citizen of the United States,and a resident of Saluda, in the county of Polk and State of NorthCarolina, have invented certain new and useful Improvements inOar-Brakes, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof, in whichsimilar letters of reference indicate corresponding parts.

This invention. relates to car-brakes, and the object thereof is toprovide an improved device of this class which is adapted to beconnected with all classes of cars, and particularly with freight andsimilar cars, and which is simple in construction and operation, and bymeans of which a car may be quickly and easily stopped.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which Figure 1 is a sideView of a section of a car and one of the brakes thereof provided withmy improvement; Fig. 2, an end view thereof, and Fig. 3 a partialsection on the line 3 3 of Fig. 2.

In the drawings forming part of this specification, A represents a carof any desired form or construction, the form shown being similar tothat of an ordinary freight-car, and a the axles of one of the trucks,said trucks being of the usual or any desired form, and connected withthe car in the usual manner and mounted on the axles Ct are the usualwheels a and in the practice of my invention I mount on said axles,outside of the wheels, a frame which consists of top and bottom bars B,which are connected by vertical cross-bars b and stays or braces 6 andeach end of the frame is provided with suitable boxes or housings bthrough which the axles pass.

The boxes or housings b are provided with upwardlydirected extensions Dwhich are provided with standards 19 which pass through the ends of thetop plate or bar B, and on which are mounted strong spiral springs O,and the upper ends of the standards b are screw-threaded and providedwith oblong nuts 0 the ends of which are connected by means of chains 0with the bottom of the car or with the truck, by means of which the endsare held in position, said chains constituting a'lock which prevents thenuts from coming 01f. I also provide brakelevers D, through the outerends of which said standards pass, and the nuts 0 are screwed down ontothe ends of said brake-levers and hold them in place, and each of saidlevers is provided with a brake-shoe d,which is adapted to bear upon theupper surface of the adjacent wheel a and the inner ends of saidbrake-levers are provided with slots d and overlap each other, andsecured to the bottom of the car A as shown in Figs. 2 and 3, arehangers E, the lower ends of which are connected by a cross-plate E andsaid hangers pass through the brake-levers D, and

mounted below said brake-levers are spiral springs F.

Mounted on the hangers E, above the ends of the brake-levers D, is avertically-movable cross-head G, the central portion of which bears uponthe ends of the brake-levers D, and secured to the bottom of the carbetween the hangers E are hangers H, between which is pivoted a lever h,to the lower end of which is pivoted a corresponding lever 71 which ispivotally connected with the crosshead G at g, and pivotally connectedwith the-levers h and h is a bar K, which projects outwardly and ispivotally connected with a depending lever 70, and the bar K is providedwith a plurality of perforations or openings k andthe lever with asimilar number of perforations it and said bar and said lever areconnected by a pin or bolt which passes through said perforations, andthe object of providing a plurality of the perforations or openings insaid bar and said lever is to provide means for properly adjusting theseparts. 1

The levers h and h constitute a pair of toggle-levers by which thecross-head G is depressed on the inner ends of the brake-levers D, andit will be understood that this arrangement of the toggle-levers andtheir connected parts, including the hangers E, the cross-head G, andtheir operative devices, is duplicated, as shown in Fig. 1, said partsbeing connected with the car over each of the axles.

I also provide a chain, cord, or similar device L, which is connectedwith the lower ends of each of the levers k, and carried out wardly andupwardly and passed over a pulley M, which is suitably supported at theend of the car, and said chain, cord, or other device L is connected, bymeans of a hook or other device 172, with a vertically-movable rack-barm which passes through suitable keepers m, and above the car or on thetop thereof is pivotally supported a lever 0, said lever being pivotallyconnected with the standard 0 and mounted on said standard is a gear orsprocket wheel 0 which is adapted to operate in connection with therack-bar m and pivotally connected with said lever is a pawl O", whichoperates in connection with said gear-wheel, an d said standard is alsoprovided with a pawl 0 which operates in connection with the rack-bar,and pivotally c011- nected with said pawl O is a rod or lever O, bywhich said pawl may be operated or disengaged from the rack-bar.

The operation will be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawings and thefollowing statement thereof. henever it is desired to apply the brakeorbrakes, the lever O is pulled backwardly, and this operation raises therack-barm by means of the gear-wheel O and by this movement of therack-bar m the lower ends of the levers 7c are pulled outwardly. Thepivoted ends of the toggle-levers h and h are also forced outwardly andthe crosshead G is depressed. The inner ends of the brake-levers aredepressed by said cross-head and the brakeshoes cl are forced intocontact with the wheels a The object of the springs O is to afiord ayielding support for the outer ends of the brake-levers D and also toassist in freeing the shoes from the wheels when it is desirable toremove the brakes therefrom, and the brake-shoes are released from theirconnection with the wheels a by raising the pawl O and reversing theoperation of the lever O, which operation depresses the rack-barin andthe springs F on the hangers E will force the cross-head G and the endsof the brakelevers D upwardly, as will be readily understood.

This device is simple in construction and operation, and by meansthereof great pressure may be applied to the wheels through thebrake-shoes (I, and the car may thus be quickly brought to a stop.

It is evident that changes in the form, construction, and arrangement ofthe various parts of my improved brake may be made without departingfrom the spirit of my invention or sacrificing its advantages, and Ireserve the right to make all such alterations therein and modificationsthereof as fairly come within the scope of the invention.

Having fully described my invention, I claim as'new and desire to secureby Letters Patent '1.
